What is the percent composition for CuBr2?
The percent composition for CuBr2 is: Cu= 28.45% Br= 71.55%
Will a precipitation occur if these substances are mixed MnCl2 Na2s?
A precipitation reaction will occur when manganese(II) chloride (MnCl2) and sodium sulfide (Na2S) are mixed, resulting in the formation of a solid precipitate of manganese(II) sulfide (MnS). This reaction can be represented by the equation: MnCl2 + Na2S -> MnS + 2 NaCl.
What is the formula of the compound between calcium and sulfur that has the percent composition 55.6 percent calcium and 44.4 percent sulfur?
The formula of the compound between calcium and sulfur with the given percent composition would be CaS. This is because the ratio of calcium to sulfur atoms in calcium sulfide matches the given percentage composition.
What is the precent composition of hydrogen in water?
The formula of water is H2O. The gram atomic mass of hydrogen is 1.008 and the gram atomic mass of oxygen is 15.999. Therefore, the mass percent composition of hydrogen in water is 100{(2)(1.008)/[(2)(1.008) + 15.999] or 11.19 %.The percent composition of hydrogen in water is: 11,19 %.
What is the percent composition of ammonium carbonate?
Ammonium carbonate has the formula (NH4)2CO3. To calculate the percent composition, you first find the molar mass of each element and then divide the molar mass of each element in the formula by the formula mass of the compound and multiply by 100 to get the percentage.
The mass percent of water in a hydrate of mncl2 is 36.41 percent what is the fomular of the hydrate?
36.41% = .3641 g of H2O 63.59% = .6359 g of MnCl2 .6359g MnCl2 x (1molm MnCl2/125.84g MnCl2)=.0051 mol MnCl2 .3641g H2O x (1 mol H2O/ 18.02g H2O) = .0202 mol H2O .0051 mol MnCl2 / .0051 = 1mol MnCl2 .0202 mol H2O /.0051 = 3.96 = 4 mol H2O Formula is: MnCl2 4H2O Manganese (II) chloride tetrahydrate
What do the reactants NH3 and MnCl2 produce?
The reaction between NH3 (ammonia) and MnCl2 (manganese chloride) produces the complex compound [MnCl2(NH3)4], known as tetraamminechloridomanganese(II) chloride.
What is the oxidation number of MnCl2?
In MnCl2, the oxidation number of Mn is +2. This is because each chlorine atom has an oxidation number of -1 and there are two chlorine atoms in MnCl2, so the overall charge must equal zero.
What is name for MnCl2?
The name for MnCl2 is manganese (II) chloride. The compound is a pink polymeric solid that is non-corrosive and non-flammable.
What is the percent composition in lithium and bromine?

What is the percent composition for 29.0 g of Argon combine completely with 4.30 g of Sulfur?
To find the percent composition, first calculate the total mass by adding the masses of Argon and Sulfur. Then, determine the percent composition of each element by dividing the mass of that element by the total mass and multiplying by 100. In this case, the percent composition of Argon is about 87.1%, and the percent composition of Sulfur is about 12.9%.
What is the percent of a composition of a compound containing 8.6g of Be and 52.4g of I?
To find the percent composition of each element in the compound, you first calculate the molar mass of Be (9.01 g/mol) and I (126.90 g/mol). Then, calculate the percent composition of each element by dividing the mass of the element by the total molar mass of the compound and multiplying by 100. The percent composition of Be is 5.14% and the percent composition of I is 94.86%.
